Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally.

Yes! Out of the current 118 known elements 92 of them are natural occurring, and 26 are man made. Only 90 of the 92 natural elements are found on Earth. The other 2 natural elements are found in space.
Elements found in nature are referred to natural elements, as opposed to synthetic, which are man made.
All the elements on the earth (excepting of course man made elements) are considered natural chemical elements.
Artificial Elements can only be made by synthesisation in a lab (by firing an atom at a projectile). Wheras natural elements can be found naturally.
There are 90 naturally occurring elements. The other 28 are synthetic. Refer to the related link for a printable colored periodic table that identifies the artificially prepared elements.
92 are natural occuring, other remaining are man made.
There are 94 naturally occurring elements on the periodic table. These elements range from hydrogen (1) to uranium (92), with elements 93 (neptunium) and 94 (plutonium) also occurring in nature, though less commonly.
Yes, it is a naturally occurring crystal composed of carbon, considered a mineral, not a compound.
